The variety and variability of life on Earth are referred to as biodiversity or biological diversity.
Biodiversity is a term that refers to genetic, species, and ecosystem variation.
Causes:
Evolution, the progressive change in which new species originate from older species, is the cause of this diversity.
Through a process known as speciation, evolution leads to biodiversity.
Evolution and diversity are the results of long-term interactions between organisms and their environments, as well as the repercussions of those interactions.
Creatures adapt to their habitats over time, and the complexity of environments available enables a diversity of organisms that already have adapted to them.
